[libvirt PATCH v2 2/5] tests: don't permit NVRAM path when using firmware auto-select

When using <os firmware='...'/> we still parse the <nvram> path,
but completely ignore it, replacing any user provided content with
a custom generated path. This makes sense since when undefining the
guest, the code to cleanup NVRAM also uses the same generated path.

Instead of silently ignoring user config, we should report an
explicit error message. This shows that some of our tests had the
bogus config scenario present.
